DESC: ProSeries .5 components are to car speakers what the silver back male gorilla is to the rest of the group - the dominant member of the species. They can handle gobs of power without distortion. And they maintain a Nebraskan-flat frequency response. Each ProSeries component system includes two Neo 5t 1-inch tweeters, several tweeter mounting kits, hardware, grilles, system-specific crossovers, and woofers designed to fit one of three factory cutouts. ProSeries rigid die-cast aluminum baskets serve two purposes. They act as a heat sink to help decrease heat and increase power handling. And they keep critical parts in perfect alignment, even when subjected to the stresses of installation and jarring road conditions.
